pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, it will result in reference leak in
Moreover, this device cannot enter the idle state and always
stay busy or other non-idle state later. So we should fix it
through adding pm_runtime_put_noidle.
